Problems solved by technology
However, the fat-soluble antioxidants having the antioxidant function of lipid components are generally not volatile, and there is a problem that sufficient antioxidant effects of lipid components cannot be exhibited in a decompression storage room maintained at a low temperature.
In addition, the installation of two boxes, a box containing a volatile freshness retaining agent and a box containing a fat-soluble antioxidant, in the decompression storage room increases the product cost and reduces the storage capacity of the decompression storage room. question

The invention provides a new refrigerator which is capable of inhibiting a volatile releasing quantity of a volatile freshness retention agent so as to reduce the loading level of the volatile freshness retention agent, and improving the volatile performance of a high fat-soluble antioxidant so as to develop the anti-oxidation effect of lipid components. A mixed freshness retention agent, mixed by the volatile freshness retention agent and the fat-soluble antioxidant inhibiting the volatile quantity of freshness retention components of the volatile freshness retention agent, is accommodated in an air-permeable first accommodation body. The first accommodation body is accommodated in a non-air-permeable second accommodation body, and a releasing control part communicating the inner part and the outer part of the second accommodation body is utilized to release the freshness retention components and the fat-soluble anti-oxidation components from the mixed freshness retention agent. The volatile performance of the freshness retention components of the volatile freshness retention agent is inhibited, and the loading level of the volatile freshness retention agent is reduced, so that the rising of the sale price is inhibited to a relatively low degree.
Description
technical field [0001] The present invention relates to a refrigerator for storing refrigerated or frozen foods, beverages, etc., and more particularly to a refrigerator provided with a freshness-maintaining component releasing box for releasing a freshness-maintaining component. Background technique [0002] In the refrigerator, a refrigerating compartment is arranged in the upper part of the insulated box, a freezing compartment is arranged in the middle part, and a vegetable compartment is arranged in the lower part. In addition, among recent refrigerators, there is known a refrigerator provided with a decompression storage room that stores animal foods such as raw meat and raw fish, and cooked vegetables such as salad and can be decompressed, unlike the storage room described above. By using a vacuum pump to decompress the decompression storage chamber, the oxygen concentration in the decompression storage chamber is reduced to realize the anti-oxidation and freshness ma...
